Micronutrients are essential components in many plant metabolic systems such as photosynthesis, cell wall formation, translocation and enzyme synthesis to name just a few. The distribution of micronutrients in soil is not uniform because of world wide variation in soil properties, which result in either deficiency or toxicity of micronutrients in soil. A lack of any one or more of the micronutrients or secondary nutrients may result in poor plant growth, vigour and failure of the fruit bunch formation.
